[HBO (Henkuma)] End of a Childhood Friendship [Nishimaru]

Reika's confession to her childhood friend Yuuta was supposed to end in romance—instead, his gentle rejection unlocks something possessive in the curvy, beauty-marked girl, who decides that if he won't give her his heart, she'll claim his body instead. Straddling the slender tomgirl and stroking him toward his first climax, she bends him over for relentless anal attention that leaves him crying, cumming, and melting into ahegao while she purrs about making it melt even more, a collar around his throat by the end. A yandere femdom spiral where sweet memories become a leash and the friendship ends exactly as the title promises.
